Footwear sole



FIG. 1 is a bottom perspective view of a footwear sole showing my new design;

FIG. 2 is a right side elevational view thereof.

FIG. 3 is a left side elevational view thereof.

FIG. 4 is a front elevational view thereof.

FIG. 5 is a rear elevational view thereof.

FIG. 6 is a top plan view thereof; and,

FIG. 7 is a bottom plan view thereof.

The broken lines immediately adjacent to the solid lines in FIGS. 1, 2, 3, 5, 6, & 7; and the polygonal and triangular broken-line Shapes in FIGS. 1 & 7, represent the unclaimed boundaries of the design while the broken lines showing the remainder of the shoe sole and upper, illustrate the portions of the design that form no part of the claim. 

I claim the ornamental design for a footwear sole, as shown and described.
